Gödde-Beton: Precast concrete parts produced sustainably

The family business Gödde-Beton GmbH emphasises sustainability – with the aim of producing maximum quality with minimal environmental impacts. With this in mind, the industrial enterprise drew up an environmental balance sheet on its precast concrete parts two years ago. Since then, Gödde-Beton has been using the results to make the work processes in its plant more efficient and climate-friendly.

Gödde-Beton GmbH inspects the sustainability of its own operations – and can thus continuously improve its performance. One way in which the company achieves this is the environmental balance sheet, whereby all emissions are compiled – from retrieval and preparation of the raw materials to the use of the precast concrete parts on building sites.

Since this was undertaken, the company knows that about 260 kilograms of CO2 are emitted per tonne of precast concrete part. Alongside the proportion of cement in the concrete, the energy consumption figures in the plant and during transportation to building sites are also accounted for. And that is precisely where the company starts applying its operational measures.

Climate protection objective:

  • Thermal insulation of the building envelope
  • Increased efficiency of plant engineering in concrete processing

Exposed concrete has many areas of application.

Resource-conserving production: Long life, regional raw materials, durable timber formworks

In many concrete products, CO2 emissions can be significantly reduced by means of a decreased proportion of cement or by using clinker-reduced cement or secondary raw materials. But when it comes to exposed concrete parts, high quality requirements prevent this. Therefore, Gödde-Beton GmbH focuses on the long life of its products and carries out intensive research on low-CO2 cement.

However, the company values resource-conserving production above all, sourcing its raw materials within the region where possible: Approximately one third of the transportation runs carried out are within a 35-kilometre radius. The water for the concrete production comes from the company’s own well.

The timber frameworks for the customised production of precast concrete parts are produced in in-house mould making and can be reused up to 50 times. If a building is being dismantled, Gödde concrete parts are fully recyclable and can be reused as secondary raw materials. If the products contain wooden components, for example benches, FSC®-certified tropical hardwood is used.

Energy efficiency and renewable energies in the plant: PV system, highly-efficient heat sources and plans for the future

Since 2014, the plant’s energy supply has been provided by a photovoltaic system that helps to reduce CO2 emissions by over 10 tonnes in its first year. With a further investment, this will increase to almost 25 tonnes per year in the future: The heat required for the hydration process is supplied by highly-efficient luminous heaters with an efficiency level of about 95 per cent. In comparison to other heating systems, this leads to primary energy savings of around 30 per cent.

In total, the company’s greenhouse gas balance sheet reported residual overall CO2 emissions for the internal processes of 210 tonnes. Gödde-Beton compensates for these emissions fully.

However, since the company has set avoiding emissions as its primary aim, Gödde-Beton GmbH has adopted additional climate protection goals. Between 2018 and 2020, the company will thermally insulate the envelope of its building. The plant engineering in concrete processing will also be improved.

Gödde-Beton GmbH produces customised precast concrete parts made of exposed concrete. Our products provide people with possibilities to congregate. Whether on playing pitches or in beer gardens – they are used to create highly diverse spaces where people can spend time. Nevertheless, we see ourselves as being faced with increasing customer requirements in the environmental area. In the era of climate change and of continually increasing energy and raw material prices in particular, this topic has taken on a whole new meaning for us.
